ABSTRACT OF THE DISCLOSURE A latching mechanism on coke oven doors, at least two latching beams being mounted on the door at different heights for movement perpendicularly to the door plane, each such beam when in the closed position engaging by way of its outer ends on hooks on the door frame, as abutment, the door being pressed against the door frame by spring forces acting on the latching beams, characterized in that the latching beams are guided for movement near their free ends in slots disposed perpendicularly to the door plane in rigid retaining members secured to the door; each latching beam is acted on by a toggle mechanism which produces a parallel movement in the slots, the toggle mechanisms are so disposed on two latching beams as to be in laterally inverted relationship in respect of the angular position of their toggle arms; and two axially consecutive spaced-apart actuating rods are provided whose outer ends are pivoted to the central articulation of a toggle mechanism and whose inner ends are connected to a common biasing element e.g. a spring, biasing the toggle mechanisms in the sense of ex- tending their arms.
